I have a Dell 15z running Windows 8.1. I want it to hibernate, not sleep, after a specified number of minutes. If I go to "Control Panel > Power Options > Change Plan Settings > Change advanced power settings > Sleep > Hibernate after," it lets me select a number of minutes and then click Apply and OK, but if I go back to look at the settings later they're always changed back to Never, the default.
Apparently Dell has had this problem on other models and has not solved it. Any suggestions?
